KClO₃, KMnO₄ va KHCO₃ aralashma qizdirildi. Kaliy permanganat parchalanishidan hosil bo‘lgan kislorod 1792 ml (n.sh.) propanning 1/4 qismini, bertole tuzidan hosil bo‘lgan kislorod esa qolgan qismini yoqishga yetarli bo‘ldi. Bunda hosil bo‘lgan CO₂ hajmi kaliy gidrokarbonat parchalanganda ajralgan CO₂ hajmiga teng bo‘lsa, boshlang‘ich aralashma massasini (g) toping.

📝 Detailed explanation

n(C₃H₈)=0,08; 1/4=0,02 propan ⇒ O₂=0,1 mol ⇒ KMnO₄: 0,4 mol (m=63,2 g). Qolgani 0,06 propan ⇒ O₂=0,3 ⇒ KClO₃: 0,2 mol (m=24,5 g). CO₂=0,24 mol = KHCO₃ dan: 2KHCO₃→K₂CO₃+CO₂+H₂O ⇒ KHCO₃=0,48 mol… hisob bo‘yicha jami ≈ 104,1 g.
